1 DLMS support

Overview
This document describes the specific implementation of the DLMS protocol, version 6, for
the A1800 ALPHA meter series 110 and later. This document, along with the documents
describing DLMS objects and the DLMS color books, provides information on
communicating with A1800 ALPHA meter series 110 using DLMS protocol.

Note: For the remainder of this document, use of the term “A1800 ALPHA meter” refers
specifically to the series 110 or later unless otherwise indicated.
This implementation of the DLMS protocol is fully compliant with the DLMS standards and
has been tested with the Certification Test Tool (CTT) version 2 provided by the DLMS User
Association (UA), of which Elster is a member.

A1800 ALPHA meter communication overview

The A1800 has 3 communication ports:
Table 1-3. A1800 ALPHA meter communication ports
Port Data rate Notes
Port 0 (optical) Fixed starting rate of 9600 bps ANSI C12.18 and DLMS protocols are
auto-detected at 9600 bps
Remote port 1 and All-session fixed data rate; data rate ANSI C12.21 and DLMS protocols are
Remote port 2 is configurable auto-detected at the configured data
rate

The ports are configured using the Metercat and MeterHat configuration software. The
frame format is, by default, as follows:

• 8 data bits
• no parity
• 1 stop bit
When using DLMS protocol with IEC 62056-21 Mode E opening, the following frame format
is accepted:

• 7 data bits
• even parity
• 1 stop bit
DLMS implementation 1-3 DLMS support

DLMS protocol configuration

The DLMS protocol can be configured using an Elster software tool. The following
parameters can be configured:

• Remote port data rate can be 2400, 4800, 9600, 14400, 19200 or 28800 bps
• The optical port has a fixed opening data rate of 9600 bps
• Physical address of the DLMS device (for 2/4 bytes addressing)
In case of 1 byte addressing (direct communication), the physical address is
irrelevant.
• DLMS passwords
The A1800 ALPHA meter currently supports only low-level security. Passwords are 20
bytes long.

Opening modes
The A1800 ALPHA meter supports two opening modes:

• IEC 62056-21 Mode E

This mode uses a 7E1 (7 data bits/even parity /1 stop bit) frame format using the
starting data rate for the selected port (that is, the data rate cannot be negotiated).
This continues with Direct HDLC, changing the frame to 8N1 (8 data bits/no parity/
1 stop bit).
• Direct HDLC
This mode uses an 8N1 frame format at the configured data rate, skipping the
Mode E preamble.

COSEM level specifics

Logical names (LN) addressing is implemented; short names addressing is not supported.
The objects list can be downloaded from the Association LN Object List (0.0.40.0.1.255).
Only full selective access is allowed for this object.

There are two clients available through two associations as follows:

Table 1-4. Available clients through associations
Association Client number Security Observations
0 16 None The public client. Only the DLMS mandatory objects, metering
point IDs, detected connection diagram, CT/VT ratio,
accuracy class, and phase rotation objects are available.
1 17 Low level All the supported objects are available.

The maximum COSEM buffer size is 512 bytes. For more information on the COSEM layer,
see the DLMS Blue Book.

HDLC level specifics

The maximum HDLC buffer size is 128 bytes. All 3 types of addressing are available:

• 1 byte
Direct access only; 1 byte for the Logical Device ID (Upper HDLC address)
• 2 bytes
The first byte is the Logical Device ID (Upper HDLC address); the second byte is the
physical ID (Lower HDLC address)
• 4 bytes
The first 2 bytes of the address are the Physical ID (Upper HDLC address); the last 2
bytes are the Logical Device ID (Lower HDLC address)

Only one Logical Device is present in the meter, and the address of the Logical Device is 1.

The Client ID can be one of the following:

• 16
Public client; uses no security; used only for very few objects (see Table 1-4)
• 17
Uses low level security (20 bytes of password configurable through a configuration
software); all the objects supported are present

The following conformance block parameters are supported by the meter:

• Block transfer with get

• Block transfer with set
• Get
• Set
• Selective access (only entry descriptor is supported)
• Action
For more information on the HDLC layer, see the DLMS Green Book.

Note: Not all the objects supported by the meter will appear in the list of objects
downloaded from the Association LN Object List. Depending on the meter
configuration, only a subset of these will be present. For example, if Load Profile is
not enabled, no Load Profile Object will appear in the Object List.

• no rights when used with client 16 (the public client)

• read rights when client 17 is used

1 0 99 129 0 255 Instrumentation Profile, set 2

2 Buffer
The data represents the intervals specified in the request. The invalid (skipped) intervals are
also present in the profile buffer and are filled with 0s. Each entry has multiple fields., and
those fields are as following:

1. capture time
• OBIS code: 0, 0, 1, 0, 0, 255
• the timestamp of the interval
2. Channel data for each channel which is configured and supported
• OBIS code: depending on LP/IP configuration

3 Capture objects
The following capture objects are present:

DLMS implementation 3-2 Profiling capture objects

4 Capture period
The profile interval size in seconds.

5 Sort method
The entries are presented in a LIFO (last-in first-out) fashion, with the newest entry first.

6 Sort object
No object to sort by.

7 Entries in use
The number of intervals (including some invalid ones) that the profile object has recorded
so far and are available through the buffer attribute.

8 Profile entries
The maximum number of entries the profile object can record. It depends on meter
configuration.

Parameterized reading of LP and IP

The profile buffer entries can be retrieved by either demanding the whole data (using 0x00
as access selector) or by doing a selective access request. In the latter case, the only
supported selective access type is the entry descriptor (using 0x02 as access selector).
Specifying the desired data is done using selectors as follows:
Table 3-3. Parameterized reading of profile selectors
Selector Description
From Entry 0: from the most recent entry
X: from entry number x, the 1st entry being the most recent entry
To Entry 0: to the oldest entry
X: to entry number x, the 1st entry being the most recent entry
From Value 0: from the start of the capture objects (time stamp)
X: from capture object number x, the 1st one being the time stamp
To Value 0: to the last capture object
X: to capture object number x, the 1st one being the time stamp

Error codes
When an error occurs during the reading of the requested profile, an error code is returned
as follows:
Table 3-4. Profile reading error codes
Error code Name Description
0 SUCCESS The reading completed successfully
2 TEMPORARY_FAILURE A new ANSI block was created making reading attribute buffer of the
capture object impossible in this attempt
3 READ_WRITE_DENIED The read/write operation is denied
11 OBJECT_UNAVAILABLE The LP/IP requested might not be configured or an error occurred
14 DATA_BLOCK_UNAVAILABLE The parameters given in the selective access are invalid

0 0 1 0 0 255 8 2 Time Stamp of the entry

4 Capture Period
No capture period is available because events are triggered by a calendar entry or by a
button press.

5 Sort Method
The entries are presented in a LIFO (last-in first-out) fashion, with the newest entry first.

6 Sort Object
No object to sort by.

7 Entries in Use
This represents the number of Event Log entries available.

8 Profile Entries
This represents the maximum number of Event Log entries that can be stored.
DLMS implementation 4-2 Event log objects

Parameterized reading of event log

The profile buffer entries can be retrieved by either demanding the whole data (using 0x00
as access selector) or by doing a selective access request. In the latter case the only
supported selective access type is the entry descriptor (using 0x02 as access selector).
Specifying the desired data is done using selectors as follows:

Selector Description
From Entry 0 - from the most recent entry
X - from entry number 'x', the 1st entry being the most recent entry
To Entry 0 - to the oldest entry
X - to entry number 'x', the 1st entry being the most recent entry
From Value 0 - from the start of the capture objects (time stamp)
X - from capture object number 'x', the 1st one being the time stamp
To Value 0 - to the last capture object
X - to capture object number 'x', the 1st one being the time stamp

2 Buffer
The number of buffer entries for the Self Read Object is determined by the maximum
number programmed in the meter and by the number of self reads performed. The
Previous Billing Object has maximum of one entry. Each entry has a time stamp and data
as described below:

1. Capture Time
• OBIS code: 0, 0, 1, 0, 0, 255
• the time stamp of the entry
2. Data for each configured quantity (summation, demand, maximum demand). If
maximum demand is configured, then 2 objects with the same OBIS code (the OBIS
code of that maximum demand object) and different attributes will be provided, one
containing the actual data and another containing the time stamp when that
maximum demand occurred.
DLMS implementation 6-2 Self reads and previous billing objects

3 Capture Objects
The following capture objects are present:

OBIS codes Class ID Attribute

Description
A B C D E F
0 0 1 0 0 255 8 2 Time Stamp of the entry
1 1 c d 0 255 3 2 Data for summation or demand (see Sources below)
1 1 c d 0 255 4 2 Data for maximum demand (see Sources below)
1 1 c d 0 255 4 5 The time stamp when maximum demand occurred (see
Sources below)

4 Capture Period
No capture period is available.

5 Sort Method
The entries are presented in a LIFO (last-in first-out) fashion, with the newest entry first.

6 Sort Object
No object to sort by.

7 Entries in Use
For Self Reads, this represents the number of self reads available. For Previous Billing this
will always be 1.

8 Profile Entries
For Self Reads, this represents the maximum number of self reads that can be recorded.
For Previous Billing this will always be 1.

Parameterized reading of self reads & previous billing data

The profile buffer entries can be retrieved by either demanding the whole data (using 0x00
as access selector) or by doing a selective access request. In the latter case the only
supported selective access type is the entry descriptor (using 0x02 as access selector).
Specifying the desired data is done using selectors as follows:
Table 6-1.
Selector Description
From Entry 0 - from the most recent entry
X - from entry number 'x', the 1st entry being the most recent entry
To Entry 0 - to the oldest entry
X - to entry number 'x', the 1st entry being the most recent entry
From Value 0 - from the start of the capture objects (time stamp)
X - from capture object number 'x', the 1st one being the time stamp
To Value 0 - to the last capture object
X - to capture object number 'x', the 1st one being the time stamp

7 Clock objects

An instance of the clock interface class handles the information about time and date
stamps. When referenced directly, the clock object specifies the time attribute of the meter.
When it is part of complex structures, such as extended register or profile generic
interfaces, the clock object specifies a time stamp.

1. Logical Name Octet-string (6) The OBIS code. - R
2. Table ID Long-unsigned The ANSI table ID. Can be a standard or a - R
manufacturer table.
3. Length Double-long- Number of octets in the table buffer. - -
unsigned
4. Buffer Octet-string (variable) An offset based selective access is used, the - R
offset in the table being double-long-unsigned
and the count a long-unsigned

Note: Only selective access is supported (offset, length). Attempting to read the full buffer
without selective access enabled will result in an error code.
